In general, we only need to monitor the program process. But this time we encountered such a problem, the company developed the program, the program process is still in progress, but the deadlock. This has caused a wide range of impact. What's even worse is that I don't know where the problem is, or what other test colleagues have helped me find out. I really lost my O M face. hellip; to avoid this situation, we analyzed the deadlock of the process and found that the deadlock will occupy 100%

Introduction of Nagios Nagios is an open source computer system and network monitoring tool, can effectively monitor Windows, Linux and UNIX host State, switch routers and other network settings, printers and so on. When the system or service status is abnormal, send an email or SMS alert the first time to notify the site operators, in the state of recovery after the normal mail or SMS notification.

After installing the COLLECTD tool on the host, you can obtain data such as cpu,memery,if-traffic of the virtual machine on the host by using the COLLECTD tool. Monitoring of these data can be achieved through Nagios monitoring scripts.The following is a simple monitoring virtual machine memory script:#!/bin/bash#desc:tocheckmemoryaboutvminstancestate_ok=0state_warning=1state_ Critical=2state_unknown=3collectd_home=/usr/local/collectdcollectd_ctl= $CO

BKJIA exclusive Article] I am a linux/unix system engineer who uses Nagios to automatically monitor the company's intranet development environment and Internet application environment. Nagios has powerful alarm functions, but sometimes our system group has this need, especially when the system is busy, we want to leave logs for analysis: whether it is under attack, the developer is not properly set, or the

... Troubleshooting: Enter the "lsntctl stop" or "lsntctl reload" command to get stuck. If the result does not appear for a long time, the system will not be able to get the result! Enter the "netstat-ntpl | grep: 1521" command to find the process Number of the listener. kill-9 stops, restart the listener, and then start tomcat. The website is accessible! Cause analysis: The database connection may fail because the listener is stuck due to a database bug! See: Post-maintenance: To avoid this pro

-maintenance: To avoid this problem as much as possible, I want to write a monitoring script in combination with nagios monitoring. When the database connection is abnormal, I can receive an alert text message as soon as possible. java programs connect to the database and use the connection pool, therefore, it may not be possible to expose problems in time! Write a script and run it in the task plan. regularly connect to the database, query the system
